chore: 代码风格统一和项目文档添加

主要变更：

1. 代码风格统一
   - 统一使用双引号替代单引号
   - 保持项目代码风格一致性
   - 涵盖所有模块、配置、实体和服务文件

2. 项目文档
   - 新增 SECURITY_FIXES_SUMMARY.md - 安全修复总结文档
   - 新增 项目问题评估报告.md - 项目问题评估文档

3. 包含修改的文件类别
   - 配置文件：app, database, jwt, redis, cache, performance
   - 实体文件：所有 TypeORM 实体
   - 模块文件：所有业务模块
   - 公共模块：guards, decorators, interceptors, filters, utils
   - 测试文件：单元测试和 E2E 测试
